需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本申请。It should be noted that the embodiments in the present application and the features of the embodiments may be combined with each other in the case of no conflict. The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
图1是本发明一实施例的基于信令数据的定位方法的流程示意图。FIG. 1 is a schematic flowchart of a positioning method based on signaling data according to an embodiment of the present invention.
如图1所示，该方法包括以下步骤：S110，利用基站对移动终端的信令软采，得到到达角度AOA的字段和时间提前量TA的字段；S120，根据AOA的字段和TA的字段，计算出移动终端相对基站的到达角和距离；S130，基于到达角和距离，计算出移动终端相对基站的在经度方向上的经度距离和在纬度方向上的纬度距离；S140，依据经度距离和纬度距离，计算得到移动终端所在位置的经度和纬度；S150，基于道路网对道路网对应的地图进行分区，生成移动终端的合理运动区域；S160，根据经度和纬度将移动终端所在位置标记在地图上，删除合理运动区域外标记的位置。As shown in FIG. 1, the method includes the following steps: S110, use the base station to softly acquire the signaling of the mobile terminal to obtain the field of the angle of arrival AOA and the field of the time advance TA; S120, according to the field of the AOA and the field of the TA, Calculate the angle of arrival and the distance of the mobile terminal relative to the base station; S130, based on the angle of arrival and the distance, calculate the longitude distance in the longitude direction and the latitude distance in the latitude direction of the mobile terminal relative to the base station; S140, according to the longitude distance and latitude distance, calculate the longitude and latitude of the location of the mobile terminal; S150, partition the map corresponding to the road network based on the road network, and generate a reasonable movement area of the mobile terminal; S160, mark the location of the mobile terminal on the map according to the longitude and latitude , delete the marked positions outside the reasonable motion area.
在步骤S110中，利用基站对移动终端的信令软采得到AOA与TA字段。其中，AOA是测量信号的到达角度。具体的，AOA为待定位终端的入射方向与正北方向夹角。TA是时间提前量。TA指示移动台提前发送的时间。TA由基站测量后通知移动台(即终端)提前这段TA时间发送数据，目的是为了扣除基站与终端之间的传输时延。例如，移动台在信道上以489ms一次的频率向基站发送指令，那么，1个TA为4.89米。In step S110, the AOA and TA fields are obtained by soft acquisition of the signaling of the mobile terminal by the base station. where AOA is the angle of arrival of the measurement signal. Specifically, the AOA is the angle between the incident direction of the terminal to be located and the true north direction. TA is the time advance. TA indicates the time that the mobile station sends in advance. After the TA is measured by the base station, the mobile station (ie, the terminal) is notified to send data in advance of this TA time, in order to deduct the transmission delay between the base station and the terminal. For example, if the mobile station sends commands to the base station at a frequency of 489ms on the channel, then one TA is 4.89 meters.
在步骤S120中，根据AOA与TA字段计算出用户所在位置相对基站的到达角
图2是本发明一实施例的终端与基站的位置关系示意图。FIG. 2 is a schematic diagram of a positional relationship between a terminal and a base station according to an embodiment of the present invention.
参见图2，L的计算公式可以如下所示：Referring to Figure 2, the calculation formula of L can be as follows:
L＝4.89×TA (1)L=4.89×TA (1)
其中，L为终端相对基站的距离，TA是时间提前量。Among them, L is the distance of the terminal relative to the base station, and TA is the time advance.
其中，
在步骤S130中，基于到达角
在一些实施例中，dx的计算公式可以如下所示：In some embodiments, the calculation formula of dx may be as follows:
dx为移动终端相对基站的在经度方向上的经度距离，L为终端相对基站的距离，
在一些实施例中，dy的计算公式可以如下所示：In some embodiments, the calculation formula of dy can be as follows:
dy为移动终端相对基站的在纬度方向上的纬度距离，L为终端相对基站的距离，
在步骤S140中，依据dX和dy计算得到移动终端所在位置的经度j与纬度w。In step S140, the longitude j and the latitude w of the location of the mobile terminal are calculated according to dX and dy.
图3是本发明另一实施例的终端与基站的位置关系示意图。FIG. 3 is a schematic diagram of a positional relationship between a terminal and a base station according to another embodiment of the present invention.
为了进一步提高用户定位的精度，优选的，可以在计算用户所在位置经纬度之前，对地球半径进行修正。参见图3，具体修正的公式可以为：In order to further improve the accuracy of user positioning, preferably, the radius of the earth may be corrected before calculating the latitude and longitude of the user's location. Referring to Figure 3, the specific correction formula can be:
其中，R极是地球的极半径，R赤是地球的赤道半径，W是基站的纬度。Among them, R pole is the polar radius of the earth, R red is the equatorial radius of the earth, and W is the latitude of the base station.
在得到经过修正的地球半径R后，可以计算出用户所在位置的经纬度。计算的公式如下所示：After obtaining the corrected earth radius R, the latitude and longitude of the user's location can be calculated. The formula for the calculation is as follows:
r＝R×cosW (6)r=R×cosW (6)
其中，r为基站的纬度圈半径，R为修正后的地球半径，W为基站的纬度。Among them, r is the latitude circle radius of the base station, R is the corrected earth radius, and W is the latitude of the base station.
在步骤S150中，对需要定位的小区进行地图预处理，依据道路网信息对所得到的用户位置信息做关联分区处理。具体分区可以进行图4和图5所示的两次分区处理。In step S150, map preprocessing is performed on the cell to be located, and the obtained user location information is subjected to associated partition processing according to the road network information. For specific partitions, two partitioning processes as shown in FIG. 4 and FIG. 5 can be performed.
图4是本发明一实施例的根据当地的道路网进行第一次分区的示意图。FIG. 4 is a schematic diagram of the first zoning according to the local road network according to an embodiment of the present invention.
参见图4，对定位地图做预处理例如可以是：先根据当地的道路网进行第一次分区，得到如图4中线条所勾画的公共区域。Referring to FIG. 4 , the preprocessing of the positioning map may be, for example, firstly partitioning according to the local road network to obtain the public area delineated by the lines in FIG. 4 .
图5是本发明一实施例的根据当地的道路网进行第二次分区的示意图。FIG. 5 is a schematic diagram of the second zoning according to the local road network according to an embodiment of the present invention.
可以在图4分区的基础上，再根据得到的用户位置信息进行第二次具体分区，如图5中线条所勾画的公共区域。该公共区域是用户合理的活动区域，该公共区域之外的区域是用户不合理的活动区域。例如，森林、湖畔、荒郊等人迹罕至的区域是用户不合理的活动区域。On the basis of the partition in FIG. 4 , a second specific partition may be performed according to the obtained user location information, such as the public area delineated by the lines in FIG. 5 . The public area is the user's reasonable activity area, and the area outside the public area is the user's unreasonable activity area. For example, inaccessible areas such as forests, lakesides, and deserted suburbs are unreasonable activity areas for users.
在步骤S160中，将得到的位置信息撒在地图上，若有位置处于分区以外，则视为无效信息，并舍弃该数据，最终实现用户定位。In step S160, the obtained location information is scattered on the map, if any location is outside the partition, it is regarded as invalid information, and the data is discarded, finally realizing user positioning.
本实施例可以应用于用户定位的场景，具体可以通过对用户随身携带的终端(例如手机)的定位来间接对用户进行定位。This embodiment may be applied to a user positioning scenario, and specifically, the user may be indirectly positioned by locating a terminal (for example, a mobile phone) carried by the user.
本实施例可以通过信令软采，得到AOA字段和TA字段，然后计算出移动终端相对基站的到达角和距离，再计算出移动终端相对基站的经度距离和纬度距离，之后计算得到移动终端所在位置的经度与纬度，可以在较低的计算复杂度下，实现用户级别的精确定位，解决了现有的只能进行小区级别的定位的精度较低的问题。另外，本实施例通过对地图进行预处理，生成移动终端的合理运动区域，将移动终端所在位置标记在地图上，删除合理运动区域外标记的位置，可以进一步提高用户的定位精度。In this embodiment, the AOA field and the TA field can be obtained through soft acquisition of signaling, and then the arrival angle and distance of the mobile terminal relative to the base station are calculated, and then the longitude distance and latitude distance of the mobile terminal relative to the base station are calculated, and then the location of the mobile terminal is calculated. The longitude and latitude of the location can realize precise positioning at the user level with low computational complexity, which solves the problem that the existing positioning can only be performed at the cell level with low precision. In addition, this embodiment generates a reasonable movement area of the mobile terminal by preprocessing the map, marks the location of the mobile terminal on the map, and deletes the marked position outside the reasonable movement area, which can further improve the user's positioning accuracy.
与传统软采集数据分析相比，上述定位方法可以将小区级定位精确到用户级。与传统技术相比，上述方法具有计算复杂度低，精确度较高的优点。另外，上述实施例提出的用户定位方法，便于操控，具有一定的可实施性及实用推广价值，因而使得本定位方法可应用于具有相关关系的软采信令数据分析中。Compared with the traditional soft collection data analysis, the above positioning method can accurately locate the cell level to the user level. Compared with the traditional technology, the above method has the advantages of low computational complexity and high accuracy. In addition, the user positioning method proposed in the above embodiments is easy to operate, and has certain practicability and practical promotion value, so that the positioning method can be applied to the analysis of soft-sampling signaling data with correlation.
下面以实际实验数据为基础，详细说明基于信令数据的定位的实现方式。Based on the actual experimental data, the implementation manner of the positioning based on the signaling data will be described in detail below.
步骤1，例如，该用户的手机的信令软采集字段：AOA为10度，TA为5米。Step 1, for example, the signaling soft collection field of the user's mobile phone: AOA is 10 degrees, TA is 5 meters.
那么该用户所在位置的到达角
用户相对基站的距离L＝4.89×TA＝24.45(米)The distance between the user and the base station L=4.89×TA=24.45 (meters)
步骤2，为了计算用户所在位置的经纬度，需要得到该位置相对基站经度方向上的距离dx与纬度方向上的距离dy。Step 2, in order to calculate the latitude and longitude of the user's location, it is necessary to obtain the distance dx of the location relative to the base station in the longitude direction and the distance dy in the latitude direction.
其中，
步骤3，对计算所需的地球半径进行修正，本实施例中基站的纬度W＝30.51441度，经度J＝114.42804度，地球的极半径R极＝6356725.00米，赤道半径R赤＝6378137.00米，修正地球半径R的计算方式如下：Step 3: Correct the earth radius required for the calculation. In this embodiment, the latitude of the base station is W=30.51441 degrees, the longitude J=114.42804 degrees, the earth'spolar radius Rpole=6356725.00 meters, and the equatorial radius Rred =6378137.00 meters. The Earth's radius R is calculated as follows:
修正地球半径后，计算该用户所在位置的经纬度。该基站所在地的纬度圈半径r的计算如下所示：After correcting the earth's radius, calculate the latitude and longitude of the user's location. The calculation of the radius r of the latitude circle where the base station is located is as follows:
r＝R×cosWr=R×cosW
＝6370877.2830×cos30.51441=6370877.2830×cos30.51441
＝5488520.2480(米)=5488520.2480(m)
用户所在位置的纬度w的计算如下所示：The latitude w of the user's location is calculated as follows:
用户所在位置的经度j的计算如下所示：The longitude j of the user's location is calculated as follows:
由此，该时刻该用户所在位置的经纬度为(114.4278，30.51616)。Therefore, the latitude and longitude of the user's location at this moment is (114.4278, 30.51616).
步骤4，对定位地图进行预处理，根据道路网进行分区，得到公共区域。再根据大量的如上述所得的位置信息对分区进行第二次处理得到用户合理的活动区域。Step 4, preprocessing the positioning map, partitioning according to the road network, and obtaining the public area. Then, the partition is processed a second time according to a large amount of location information obtained as above to obtain a reasonable activity area for the user.
步骤5，用户的位置信息撒在经处理后的地图上，将处于分区外的位置信息视为无效数据，并舍弃。Step 5, the user's location information is scattered on the processed map, and the location information outside the partition is regarded as invalid data and discarded.
本实施例可以通过信令软采，得到AOA字段和TA字段，然后计算出移动终端相对基站的到达角和距离，再计算出移动终端相对基站的经度距离和纬度距离，之后计算得到移动终端所在位置的经度与纬度，可以实现用户级别的精确定位，解决了现有的只能进行小区级别的定位的精度较低的问题。另外，本实施例通过对地图进行预处理，对用户合理的活动区域进行分区，可以将不合理的数据进行剔除处理，提高了定位的精度。In this embodiment, the AOA field and the TA field can be obtained through soft acquisition of signaling, and then the arrival angle and distance of the mobile terminal relative to the base station are calculated, and then the longitude distance and latitude distance of the mobile terminal relative to the base station are calculated, and then the location of the mobile terminal is calculated. The longitude and latitude of the location can realize precise positioning at the user level, which solves the problem that the existing positioning can only be performed at the cell level with low precision. In addition, in this embodiment, by preprocessing the map and partitioning the reasonable activity area of the user, unreasonable data can be eliminated, thereby improving the positioning accuracy.
